' SLIDE CONSTRUCTION.

Application filed March 23-, 1925. Serial no. 17,-50o.

.To (HZ 107mm itmay concern: Y

Be it known that I, GEORGE'E. PRENTICE, a citizen ofthe United States,residin at Berlin, in the countyof Hartford and State of Connecticut,have invented certain new and useful Improvements in Slide Construction,of which the following is a specification. Y

My invention relatesto improvements in slide construction, of the formthatis used to I effect the connection and disconnection ofintel-locking fastener devices that are disposed along the opposed edgesof fabric strips or a the like and. which edges define theborders of agap or opening in a garment, shoe, or container or the like, and of thegeneral form as the slides that are shown and described in myco-pendingapplications filed April 28, 1924, Serial No. 709,643, and August 29,1924, Serial No. 735,01 and the object of my improvement is top'rovide aform of construction involving the usual wings that are opposed andspaced one from the other to cooperate with the fastener devices and inwhich the pull or handle structure is so mounted as to reduce to aminimum the tendency under operating conditions for the plates to openout or spread apart and therec and with the upper plate removed.

' Figure 3 is a top view of the slide. Figure 4 is a bottom view of thesame. Figure 5 is a sectional view on the line 5-5 of Fig. 1. I I IFigure 6 is a plan View of the blank for i the plate member.

My improved slide 10 operates substantially in the same manner as theslides that are shown and described in the different applicationsreferred to above for the purpose of bringing into interlockinglengaement and for disengaging interloc vicesll that are disposed. along theborder edges 12 of strips 13 of fabric or the like'by means ofa'slidingmovement in one direcfor the springs.

astener de-' tion or'the other. The fastener devices 11 in each case areparts of a'single coil spring,

comprising the left spring 14 as shown in Fig. 1 and the right spring15, thesaid springs being threaded through the material of the strip 13so that the parts 11 of the SPl'lIlgStlltl-t serve as to activeinterlocking parts or. devices lloverhang the edge 12 as mentioned.

The upper portions of the springs 15 are separated, as shown, and thelower parts, below the slide 10 are interengage d,

Movement of the slide lOupwa-rdly serves to bring together into lockingengagement the parts of the springs that are housed within the slide.The springs 14 and 15 emerge from the upper end portion of the slide 10through individual openings 16, one for each of said springs, and whichopenings 16 are spaced-laterallone fromthe other. At the lower endportion of the slide 10 is a single opening 17 in which is positionedthe interlocked structure that consists of the ad-'.

jacent interlocked portions of the two springs. r The openings 16 and 17are defined at the plate 18 and the back plate 19, said beilpgpositioned in spaced relation.

plates 14 and ant flanges 20 are provided along the I lateral edges 21of the upper plate'18, ex-

'front' and back respectively by the front. 1

tending-from the upper 0 enings 16 to the v low-er opening 17, and saidflanges 20- co- 0 erate with the adjacent portions of the p ates 18 and19 to form an operating Chan! nel on each side for the correspondingspring I 14 or 15 for use when the slide is moved in one, particulardirection. The articular channels 22 referred to may be designated asthe lower channels 22 and they function when the slide 10 is lifted ormoved up: wardly so as to bring the springs 14 and 15 together, and inwhich movement the springs engage with the pendant fianges'20 and theadjacent and cooperating portions of the plates 18' and 19 operate aslateral guides The upper end portions 23 of the channels 22, adjacentthe upper' spring andextending upwardly from said lower opening-17,overlap one another, as do the s rings or the parts thereof that arehoused t 'erein. The two channels 22 merge toform receiving openings 16,are convergent, extending downwardly and, inwardl and the lower endportions, adjacent the ower opening 17,

a relatively wide channel 24 that has parallel side walls, as defined bythe adjacent portions 25 of the flanges 20. The upper portions 26 of theflanges are convergent.

tive bottoms or end walls.

Said bottoms are defined at the upper ends, from the sides of theopenings '16 inwardly, by the inwardly directed wings 29 and thejunction of the two upper channels 28.is virtually determined by thecentrally disposed pin or post 30 .that constitutes the body portion ofa rivet structure that passes through openings 31 in the two plates 18and 19 and which will be more fully de- I scribed.

The upper plate 18 and lower plate 19 are parts of a blank 32 of sheetmetal that is provided with a return bend along a neck structure thatserves to interconnect the two plates. The wings 29 above referred toare connected with the neck 33 along the lateral edges 34 thereof andare turned inwardly to the guiding position for cooperating with thesprings 14 and 15.

The rivet, body 30 has a head 35 at the rear end that is opposed to therear plate 19 and opposed to the front plate 18 there is a cooperatinghead-like structure that isv defined as a shoulder or overhanging part36. Said rivet body 30 and the holes 31 therefor are of square form soas to posi-,

tively position the rivet structure 37 as awhole relatively to theplates 18 and 19. Said rivet body is projected forwardly from theshoulder 36 and the front plate 18 and at the forward end comprises adownwardlydirected branch 38 that extends along in front of thev frontplate 18 and in spaced relation thereto and which at its lower end isprovided with an inwardly or rearwardly directed tip or point 39. Thusthe part 40a of the rivet structure 37 in front of the shoulder 36 is ofa modified U-shape and on this part is mounted for substantially freemade with the end wall 43 adjacent the shoulder 36 and for downwardmovement contact is made with the tip'or nose 39.

Said tip or nose 39 has the free end ll opposed to the face of thefrontplate '18, and is free from any direct or positive connection therewith.

Thus in the cases of the different movements and manipulations 'of thehandle for moving the slide all of the strain will be 'confined to thestructure of the rivet and there will follow no tendencyto distort theplates or the general structure of the slide. The plates 18 and 19 areprovided, as

shown, each with a longitudinally directed strengthening rib 45 that isformed by indenting the material are formed.

I claim as my invention a 1.
